Is there some connection between the reason balls spin and planets etc. in space? I ask this as a layman, who has noticed that balls travelling through the air rotate, whether thrown or kicked (Using a dog ball thrower this can be observed because when the ball hits the water, which acts as a brake, it is still turning; likewise a bouncing ball can be seen to spin).

Another observation that may be related to this is pushing a flat bottomed object over grass as opposed to ice. When travelling over the latter, the natural inclination is for it to spin,to maintain forward motion because of gravity causing friction, which is reduced when travelling over ice.

This ties in with my thread 'Why do UFO's spin?' in The Strange Claims forum as I'm speculating if there could be a connection between all these phenomena theoretically, even if Flying Saucers may not have been proved to be objectively real and not all incidents report this kind of movement either.
